FAQ

Q: How do I know if this valve fits my Yanmar engine?
A: This valve is specifically designed for the Yanmar 4TNE88 engine model. To confirm fitment, locate the engine model plate on your equipment (usually on the valve cover or engine block). If your engine is a 4TNE88, and your old valve has the part number 129150-13350 or 129150-13351, this part is a direct replacement.

Q: What is included in the purchase? Is this for one valve or a set?
A: The product weight is listed as 1 kg, which typically corresponds to a complete set of 8 valves (4 intake and 4 exhaust) for a 4-cylinder 4TNE88 engine. Please verify the quantity with our sales team before ordering if you require a specific number of individual valves.

Q: What maintenance should I perform when replacing engine valves?
A: When replacing valves, it is highly recommended to also replace the valve stem seals and inspect the valve guides for wear. After installation, the valve clearance (lash) must be adjusted to the manufacturer’s specifications to ensure proper engine operation and prevent premature wear. We recommend having this work performed by a qualified diesel mechanic.
